BETONCORD/10
BETONCORD/10 is a specialised concrete injector hose in NR/SBR with PN 10 bar working pressure and 30 bar burst pressure. Wear resistance is confirmed with abrasion value 70 mm3 per ISO 4649 - a heavy-duty rating that makes the hose well-suited to wet concrete, mortar and other abrasive liquids. Both inner tube and outer coating are electrically conductive (below 10⁶ ohm), providing ATEX-related safety advantages in concrete pump and injector systems. Typically used for shotcrete tunnel construction, concrete pumping at construction sites and mortar distribution in renovation.

Why this hose?
Wear resistance is BETONCORD/10's primary value proposition. Abrasion value 70 mm3 per ISO 4649 is better than ordinary industrial hoses (150-200 mm3), and the difference is decisive in concrete applications where every particle passage wears a little from the inner wall. The NR/SBR blend is the specific material that makes this difference - other rubber types would fail faster.
The electrically conductive wall (below 10⁶ ohm in both core and cover) is a safety advantage in concrete pump systems. High-pressure spraying of concrete can generate static electricity, and a conductive hose discharges the charge to ground. This is particularly valuable in tunnel shotcrete where fire danger from fuel-derived substances may be present.
The construction with wrapped outer coating and textile plies is optimised for the mechanical impacts typical of concrete work - tensile load from hose handling, pressure cycling from pump activations and contact wear against casting elements. It is a compact design package that distinguishes itself from ordinary industrial hoses.
Where it is used
Tunnel shotcrete applications are the classic use. A typical shotcrete installation has a mobile pump with 5-15 m of BETONCORD/10 from pump to spray gun. The hose's flexibility allows spraying to be performed close to tunnel walls, and wear resistance ensures the hose lasts a full workday without the wall being breached.
Construction sites use the hose in mobile concrete pump operations where concrete is transported from trucks to distant casting areas. The 40 m standard roll typically covers an entire pump installation length without joints, reducing leak risk and simplifying installation.
Industrial mortar and specialty concrete applications (sealing mortar, high-pressure renovation spraying) use the hose in ad-hoc installations. The conductive wall is safety in industrial zones, and the NR/SBR construction resists the varying mortar formulations typically found in renovation projects.
The hose is colloquially known as a concrete hose, shotcrete hose or mortar hose.
Technical specifications
The hose's key specifications are briefly summarised below. The hose is specifically designed for wet concrete and mortar - the reduced abrasion value (70 mm3) is better than most alternative hoses.

Dimensions and ordering
The table shows the hose's 2 standard dimensions. Both have the same pressure rating (10 bar PN, 30 bar burst), but the 63 mm version has greater wall thickness (13.5 mm) for extra wear margin in the most abrasive applications.

Industries that use it
BETONCORD/10 is used where abrasive liquid media such as concrete, mortar and similar must be pumped under pressure - typically in construction, tunnel and mining industries.
Tunnel construction and mining use the hose for shotcrete applications where wet concrete is spray-deposited against tunnel walls or mine surfaces. The hose's 10 bar working pressure covers typical shotcrete pump pressures, and wear resistance (70 mm3) ensures the hose can handle the sharp particles in sand and cement mixtures.
The construction industry uses the hose for concrete pumping from mobile concrete trucks to casting areas. Pressure typically varies 5-10 bar in traditional pump systems, and the hose's heavy-duty construction provides good service life in frequent use. The conductive wall is a plus property at construction sites where other flammable materials may be nearby.
Renovation and industrial mortar distribution use the hose to lead mortar and plaster products between mixing units and application stations. The specialised construction (NR/SBR with textile plies) is designed for continuous operation with abrasive media - in contrast to standard industrial hoses that would degrade in the same environment.
Custom lengths and assemblies
The hose can be delivered cut to desired lengths. The standard roll can be supplemented with shorter pieces or multiple rolls by arrangement.

Frequently asked questions
What is BETONCORD/10 particularly suitable for?
The hose is built specifically for concrete injection and mortar distribution - one of the industry's most abrasive liquid applications. The NR/SBR lining tolerates the sharp sand and cement particles in wet concrete without the wear groove opening quickly. Working pressure is PN 10 bar with 30 bar burst pressure - a safety factor of 3x.
What does abrasion value 70 mm3 mean?
Abrasion value is a standardised wear test per ISO 4649 (formerly DIN 53516). The number 70 mm3 indicates how many cubic millimetres of material are worn away under standardised test conditions - the lower the number, the better the wear resistance. 70 mm3 is a confirmed heavy-duty rating; ordinary industrial hoses typically lie at 150-200 mm3.
Why is the hose electrically conductive?
Both inner tube and outer coating are qualified as electrically conductive (below 10⁶ ohm). This is a special safety property in concrete applications where pump and injector systems can build up static electricity under high-pressure spray. The conductive wall discharges the charge to ground and prevents spark-induced ignition in ATEX-related zones.
How many dimensions are in the range?
2 dimensions: 60 mm and 63 mm inner diameter. This is a specialised range focused on the typical dimensions for concrete injector systems. Both have the same pressure rating (10 bar PN, 30 bar burst) and 40 m standard roll length.
What is the difference between 60 and 63 mm?
The main difference is wall thickness: 60 mm has 10 mm wall, while 63 mm has 13.5 mm wall. This gives the 63 mm version greater wear margin and longer service life in very abrasive applications. 60 mm has slightly better flexibility and lower weight per metre.
How long does the hose last?
Service life depends primarily on wear - each time abrasive particles pass through the hose, a small amount is removed from the inner wall. In typical concrete injector operation the hose can last 6-18 months depending on particle size, flow rate and operating pressure. Annual visual inspection for inner wall thickness is recommended.
Which couplings are recommended?
For concrete injection, metal crimp clamps or heavy-duty Storz/Bauer couplings with wear-secured rings are recommended. Standard worm-drive clamps are NOT sufficient for concrete pressure cycles. We typically fit couplings to the hose by arrangement.
Can the hose be used for dry media?
The hose is primarily designed for wet concrete and mortar - where sharp particles are surrounded by cement paste. For dry abrasive media (sandblasting, granulate transport) we recommend specialised hoses like TURBOCORD or SILOFLAT/DISCHARGE which have construction optimised for dry media handling.
